Portable asphalt storage tank at a hot mix asphalt plant.

The Heli-Tank unit combines a hot oil heater with a portable heated asphalt storage tank. Available in six different sizes with capacities from 10,000 to 35,000 gallons. Numerous options are available.

Heatec also offers portable models of its Welbilt asphalt storage tank (without integral hot oil heater), and portable direct-fired asphalt storage tanks.

Heating coils
The storage tank of the Heli-Tank unit has serpentine heating coils. Liquid asphalt in the tank is heated by hot oil flowing through the coils. The coils are formed into three layers, each with ten coils. Coils are made from rugged 2-inch schedule 40 seamless pipe and run the full length of the tank or compartments. The accompanying table shows surface areas of the heating coils in each tank model.

Capacities shown are nominal capacities. Weights are approximate and include HCS-100 heater plus optional plate foundations (1,000 lbs each), metering package (1,550 lbs) and unloading pump package (1,050 lbs). Rear frame extension adds approximately 7 feet to overall length.

Hot oil heater
The standard hot oil heater for Heli-Tank units is a Heatec Model HCS-100. Other models are optional. The heater can be used to heat another coil tank, an asphalt metering package and liquid asphalt lines. When furnished with an optional manifold and auxiliary pump, the heater can also heat silo cones, traverse conveyor and a drag conveyor.

The heater has a highly efficient helical coil. Coils are built to ASME standards and can be code-stamped as an option. Coil has a 5-year warranty for HC-series heaters (3-yr. for HCS). Coils are stitch-welded to eliminate gaps between the turns so heated gases can't short-circuit and waste energy. Optional STACKPACK economizers further increase heater efficiency.

Heaters include insulated heat chamber, centrifugal pump and expansion tank. A low-maintenance burner and controls are also included. Standard burners use No. 2 fuel oil. Optional burners are available for natural gas or for combination gas/oil.
